Whipped is just a different flavor of flavored vodka, it's Pinnacle. They have a bunch of flavors, like cherry, Strawberry kiwi, cake, Strawberry shortcake, orange whipped, chocolate whipped, etc. There's a ton. Check it out:

Mmm they even have pumpkin pie. Oh my god. :drool2: I must find that. Peachberry cobbler sounds good too.
Hmm... I may have to look into that. I've never given much consideration to flavored vodka since, as said, I tend to mix drinks and plain generally works best for that.
